Methods for phonetic information signaling

Abstract

The invention is: A method for decoding a service guide associated with a video bitstream comprising: (a) receiving a content fragment within the service guide, (b) receiving a name element within the content fragment, (c) receiving a description element within the content fragment and (d) decoding the service guide.

The invention claimed is: 
     
       1. A method for decoding a service guide associated with a video bitstream comprising:
 (a) receiving a content fragment within the service guide; 
 (b) receiving a name element within the content fragment, 
 wherein the name element is an extended name element which includes sub-elements to indicate name and phonetic information about the name element, the name element contains the sub-elements including a first SpeechInfoURI element and a first SpeechInfo element, and the name element includes a first text attribute which is a name of a service with a data type of string, 
 wherein the first SpeechInfoURI element is a URI address where a first SpeechInfo object for the name element is acquired, and the first SpeechInfoURI element includes a first content-type attribute and a first content-enc attribute, wherein the first content-type is a content-type of the first SpeechInfo object referenced by the first SpeechInfoURI element and the first content-enc is a content encoding of the first SpeechInfo object referenced by the first SpeechInfoURI element, and 
 wherein the first SpeechInfo element is embedded speech information object for the name element, and the first Speech Info element includes a second content-type attribute and a second content-enc attribute, 
 wherein the second content-type is a content-type of the first SpeechInfo object and the second content-enc is a content encoding of the first SpeechInfo object, 
 (c) receiving a description element within the content fragment; 
 wherein the description element is an extended description element which includes sub-elements to indicate description and phonetic information about the description element, the description element contains the sub-elements including a second SpeechInfoURI element and a second SpeechInfo element, and the description element includes a second text attribute which is a description of the service with a data type of string, 
 wherein the second SpeechInfoURI element is a URI address where a second SpeechInfo object for the description element is acquired, and the second SpeechInfoURI element includes a second content-type attribute and a third content-enc attribute, wherein the third content-type is a content-type of the second SpeechInfo object referenced by the second SpeechInfoURI element and the third content-enc is a content encoding of the second SpeechInfo object referenced by the second SpeechInfoURI element, and 
 wherein the second SpeechInfo element is embedded speech information object for the description element, and the second SpeechInfo element includes a fourth content-type attribute and a fourth content-enc attribute, 
 wherein the fourth content-type is a content-type of the second SpeechInfo object and the fourth content-enc is a content encoding of the second SpeechInfo object, 
 (d) decoding the service guide. 
 
     
     
       2. A decoder for decoding a service guide associated with a video bitstream comprising:
 a receiver configured to receive a content fragment within the service guide, a name element within the content fragment and a description element within the content fragment, 
 wherein the name element is an extended name element which includes sub-elements to indicate name and phonetic information about the name element, the name element contains the sub-elements including a first SpeechInfoURI element and a first SpeechInfo element, and the name element includes a first text attribute which is a name of a service with a data type of string, 
 wherein the first SpeechInfoURI element is a URI address where a first SpeechInfo object for the name element is acquired, and the first SpeechInfoURI element includes a first content-type attribute and a first content-enc attribute, wherein the first content-type is a content-type of the first SpeechInfo object referenced by the first SpeechInfoURI element and the first content-enc is a content encoding of the first SpeechInfo object referenced by the first SpeechInfoURI element, and 
 wherein the first SpeechInfo element is embedded speech information object for the name element, and the first Speech Info element includes a second content-type attribute and a second content-enc attribute, 
 wherein the second content-type is a content-type of the first SpeechInfo object and the second content-enc is a content encoding of the first SpeechInfo object, 
 wherein the description element is an extended description element which includes sub-elements to indicate description and phonetic information about the description element, the description element contains the sub-elements including a second SpeechInfoURI element and a second SpeechInfo element, and the description element includes a second text attribute which is a description of the service with a data type of string, 
 wherein the second SpeechInfoURI element is a URI address where a second SpeechInfo object for the description element is acquired, and the second SpeechInfoURI element includes a third content-type attribute and a third content-enc attribute, 
 wherein the third content-type is a content-type of the second SpeechInfo object referenced by the second SpeechInfoURI element and the third content-enc is a content encoding of the second SpeechInfo object referenced by the second SpeechInfoURI element, and 
 wherein the second SpeechInfo element is embedded speech information object for the description element, and the second SpeechInfo element includes a fourth content-type attribute and a fourth content-enc attribute, 
 wherein the fourth content-type is a content-type of the second SpeechInfo object and the fourth content-enc is a content encoding of the second SpeechInfo object, and 
 the decoder is configured to decode the service guide.
